Workaround

Note: Until the Plesk bugs will be fixed, it’s recommended to deploy a Plesk server with 1000 domains maximum. Consider migrating the extra domains to new Plesk servers to get better performance.

As a workaround for Plesk servers hosting 1000 domains or fewer:

To reduce the load time for the Domains tab

Log in to Plesk GUI
Go to Domains.
Set Entries per page value to 10 or 25:

To avoid high load time when accessing customer’s panel

Log in to Plesk GUI directly with the corresponding login and password from the customers instead of log in to the customer panel logged in as a Plesk administrator
